DE2610648A1 - Balanced organic-mineral fertiliser - contg. animal dung, rock flour and kieserite - Google Patents

Abstract

Organic-mineral fertiliser, for all agricultural and horticultural crop plants (esp. difficult food plants), has a harmonic content of constituents with plant-physiological activity and consists of a mixt. of animal dung, rock flour and kieserite. The combination of rock flour and kieserite binds the water content of the animal dung (esp. poultry manure), bringing biological processes to a halt and eliminating adour and similar problems without actually killing the microbes contained in the dung. Since poultry manure is generally low in magnesium, addn. of the Mg-contg. kieserite converts it into a balance fertiliser.

Description

Organic-mineral fertilizer

The invention relates to an organic-mineral fertilizer @ ittel for all agricultural and horticultural cultivators, especially for the discerning Food plants, with a harmonious content of plant-physiologically effective ingredients.

In the case of intensive use of the soil, one is considered sufficient fertilization with core and trace nutrients essential to maintain yield security there must no longer be enough farm-own fertilizers available for this these are supplemented by commercial fertilizers, usually mineral fertilizers.

Mineral fertilizers are products obtained in factories or mines and can be combined to form complete fertilizers through a suitable mixture These types of fertilizers represent substitutes for the natural farms Fertilizers, with their own advantages and disadvantages. Nutritional salts can against the fertilizers produced on farms. and administered in higher concentrations than is possible with the latter At the same time, too high a dosage can cause negative effects of the salts te arise that hardly occur with the company's own fertilizers, not least by the fact that the organic matter contained therein in connection with the resulting humus has such a buffering effect that even yrosse Amounts of salt can still be tolerated harmlessly by the plants. A mixture of organic and mineral fertilizers is therefore generally considered to be the ideal combination In B # operations without their own fertilizers, an attempt is made to use the Sowing short-term green plants to compensate for the deficit in organic matter.

In livestock farms with an industrial character fall today Large amounts of feces or manure can only be found in the rarest of cases because of the Specialization of the farms to be used as farm-own fertilizer.

Despite the knowledge -the good quality of such products fails a sensible use usually on the one hand on the long transport route of the fresh Materials, on the other hand, on the odor nuisance of the environment. Chicken droppings in particular should be viewed from this point of view.

The problem of transporting chicken excrement has been tried to solve when the water has been withdrawn from him in drying plants to the extent that this is economical appeared justifiable, at the same time the losses to the particularly valuable had to be easy soluble nitrogen components are kept as low as possible This process of disposing of the chicken droppings has met with poor success was, is due to the fact that the elimination of odor nuisance only very @@ completely succeeded, because the dry excrement was caused by the remaining water content was still so biologically active that the odor threshold, which humans perceived as unpleasant The material is stored under these circumstances under no circumstances into consideration.

It is an object of the present invention to provide one possibility to find the disadvantages identified when transporting and storing the chicken droppings to eliminate, keeping the biological activity and fertilizer value to the maximum should stay.

The solution to the problem consists of a mixture of animal droppings and rock flour and kieserite.

By adding absolutely dry, silicate, mineral-rich Rock meal was bound to the water remaining in the chicken droppings in such a way that the biological Activity could be reduced so much that the taking place in it and for Biological conversions leading to odor nuisance largely came to a standstill without that this was accompanied by the killing of the microorganisms The naturally magnesium-poor chicken droppings used magnesium salts as fertilizers so improved that the resulting product from an agricultural chemical point of view can be regarded as a fertilizer with a balanced fertilizing effect.

Preferably the fertilizer is by a mixing ratio of 50-80 Animal droppings to 40-lo rock meal labeled to 3 kieserite.

The fertilizer has a plant-physiologically effective content in the nutrients N P2O5: K2 0: Mg averaging 0.7: o.9: 1.5: o.6 5o excels, in addition there is a balanced content of essential trace elements which the fertilizing effect is rounded off. Its organic mass of on average almost 60 C / o with a carbon content of 27% justifies the name organic fertilizer. The total content of the core nutrients N, P205 and K20 is 1.5%, 2.4 O / a and 1.5% and thus corresponds to the declaration of an organic-mineral Fertilizers in accordance with the Fertilizers Act of August 14, 1962, published in the Federal Law Gazette Part 1, No. 35 of August 24, 1962, page 558, quoted from "The fertilizer law with technical Explanations, edition 1975, IXJ, number 1, page 118 ".

Recipe: 70 kg dry chicken droppings'2o kg high-silicate volcanic rock flour, 3 Kg Kieserite (MgSO4 X 1 -: I20) The examinations of the prepared according to the recipe Product according to agricultural-chemical aspects achieved this in the following The result compiled in Table 1. The analytical data of the naturally moist product were converted to the absolute dry matter in order to make a comparison basis with later analyzes to be carried out or with similar materials.

The content of easily soluble nitrogen results from the sum Ammonia and nitrate nitrogen as well as from around 20% of the remaining amino nitrogen, see above that this results in a total quantity of about 675 mg nitrogen / loo g, which in the First year of vegetation takes effect. From the remaining amino nitrogen can in the following year again with a share of 15-20% of what is available to plants Nitrogen can be expected.

The following relation of the main nutrients results to one another: nutrients N: P205 K20 L 2. g relation 1: 1.3: 2.2: 0.9 Gena @ t in% 0.7: 0.9: 1.5: 0.6 This relationship between the individual nutrients is physiological to the plant extremely cheap and corresponds to a harmonious complete fertilizer.

The C: N ratio is close and can be equated with that of a good compost.

The nutrient content is weakened compared to normal chicken droppings compensated by a slightly higher effort.

On the other hand, the optimization of the magnesium content makes a significant difference improved plant nutrition. This mainly affects the filr human Diet provided herbal products as it is known that many of the Civilization diseases can be attributed to a magnesium deficiency is causally related to the fact that our cultivated soils through the long-term dominant potassium fertilization are more or less depleted of magnesium.

The fertilizer according to the invention is used in all agriculture and horticulture to be used in quantities of up to 100 kg / looqm.
